A high-quality ellipse detector based on arc-support line segments which can both accurately and efficiently detect ellipses in images.
Hi, I would like to test your algorithm with Octave instead of Matlab. Nevertheless, I have some difficulties to create the mex file with the command mkoctfile. Indeed, the compilation...
您所做的研究非常nice。 以下是我的问题： 为了提升检测精度，需要处理的图像分辨率为5000x5000。 我将图像下采样至1250x1250，检测效果十分好，可以准确定位图中的圆； 但是使用原始图像，检测速度很慢，且并不能出结果，请问如何处理这样的问题。 另一个问题： 如果图像中只存在一段圆弧，圆的整体大部分在图像外（比如圆心在图像外）， 该算法可以检测出这种圆吗？ 不论是否答复，都十分感谢~
This is a cool repo, but Matlab is beyond the reach of most users. Is it possible to develop a Python 3.7 implementation? Thanks much.

You mentioned in your paper: "deep learning based methods can provide image proposals which contain oval objects for image pre-processing while they are still inappropriate to directly handle ellipse detection...
This work is very helpful and performs well in most situations. However, when I tried to detect the ellipses in a series of images, very different results showed up for...
I noticed that the algorithm produces different results on the same image when rotated by 90° or 180°. Reproducing steps: - Take an image, e.g. 35.jpg from the examples, execute...
